Re: Short-lived
Of course being Jupiter sized, it must also have a Jupiter type gravity, which coud be enough to keep itself intact....
But over time, it's local star (being bigger/heavier) will no doubt win the battle.
I suspect that we're living at a time after which this Jupiter-like planet has moved orbit towards its Sun but unlike our Solar System, there's not been any other celestial body" around to fling it back outwards.
